To all whom z'mag/ concern:

a citizen of the United States, and a resident of Whitinsville, in the county` of Worcester and Commonwealth of Massachusetts, have inventedcertain newl anduseful Improvements in LapfMachin'es, ofwhichthe ollowing is a full, true, and concise speciiczdion;`

The invention is `an improvement in lap machines for winding cottonvinto rolls for, use on combing or other machines, and/the obj ect of the improvement is to `provideniore efficient means for holding the spool whilel being wound and also ready meansfordot-- ing the same when required. L

The invention is applicable to existing man chmes without rearrangement of parts, Vand is herein shown asapplied to anordinary;

cotton lap head of familiar construction.

In the usual construction of lap heads the lap spool is held in operative position on the winding drums by means of a spindle loosely passing through the spool and screwedy into the hub of the lap guiding disk. When it is desired to remove the spool for dong, or otherwise, the operative unscrews the spindle and then withdraws it from its position inside of the spool, this operation necessitates considerable exertion on the part of Vthe operative as it frequently happens that the parts become locked together rendering it Y very ditlicult to separate them. invention eliminatesI this diiiiculty..`

With the above obJect in view, my invention consists of the novel features of con-v struction and the combinationofparts hereL inafter fully described and claimed, and il'lus-I trated 'in the accompanying drawings, in;

Figure 1 yis a front elevationlof the sliver lap machine vwith my improvements applied thereto; Fig. 2 is `a side elevation of the same; Fig. 3 is a-partial sectional view* of the lap spool holding and doiting means showingv showing keyways which actin conjunction" with means for locking the disk to the spool..

yiatentednvpas,19195, Application mea June 1c, 1917,.r sriai-Np.'1ij5,1e2. i' f imparted to the sliver while-beingfwound on the spools byJ the brakeB actingon the'slid- 6 and' racks 7, in manner well known.

.The spoolis `held between lap guidingn disks 8 and Q. providedy with hollow sleeves 10 v mg bearings 4 throughthe pulley 5,4 pinions Y which serveas" journals for thedisks to rothekeywaysl and'16 in the. disk sleeveand spool `f bushing respectively. Normallyy thef spindles are held in a locking relation .with the disksdand spool due to the compression springs 17 exerting pressure between the shoulder 18 on the spindle and collar A19 fas-lv tened to the bearing 4.

VIn the operationof dong lor releasing the spool. the spindles :13 are simultaneously withdrawn from 'engagement with the spool bushings 12 by means of the manually op'-Y erated lever 2O acting' in kconjunction with" the ,doihng levers 21 and 22 fulcrumed onx studsQS kand 24 respectively, said studs be-'kr i` ing in a fixed relation to the top of the slidl ing bearings ,4. The lower ends of theu d'oiingvlevers are formed with yokes 251 which embrace grooves' 26' in' the heads ,of the dofling spindles 13. The arms of the yokes are provided with oppositelylocated pins 27 whichengage with theshoulders of the grooves' whereby any motion impartedV tothe doi'ling levers is transmittedI to the 'doiing spindles.- The upper part of. the

doiing levers are of such length as-tocross each other atfthe' center` of the machine vforming in the normalposition-,of the levers 'a V. shaped pocketQS for contact with they hand leverQO. The upper part of the dofEng p i leveraQQfis fork shaped, within the tines of which the upper endof the other doiling ioorfn lever"l is con'iined. 'When thedoliing levers` aredepressed .for the purpose of doiiing afy lap, a lock is provided to held the' levers in thedepressed position therebyallowing ,the

operative the free use of bothhands' for removing the full lap and replacing withu an empty spool; A specific form of this lock-j ing means is shown in Figs; 4 and 5. f It consists 0i -a spring actuated ',pin 29 slid#y ably mounted in the' boss 30 located on the side of the fork of doiling lever 22. When i Vthe doiling levers are depressed to full extent the pin 29 slides into an opening 3l in end of doiiing lever 21 thus locking the levers from further movement, until the pin is withdrawn from connection by Ythe operative.

Therhand lever 20 is iixed'to the shaft l32 in swinging relation toits supportingV stands 33 xed on top ofthe sliding'bearings 4'. Normall the lever is held out of Contact with the do ng levers by the counterbalance armV 341. When it is desired todoti" the lap th'e operative swings the lever 20 in Contact with the dohng levers at their` intersection 28, presses down'thereon until the doiiing levers are in position shown in dotted lines in Fig. l; this operation withdraws the spindles 13thus releasing the lap spool so that it may be readily removed.

y I YdoV notY limit myself to the details of construction here shown, as the same may be variously modified without departing from f the spirit of my invention.V Y

Having thus explained'the nature of theY invention and described away ofconstruccopies f this Ypatent may be attained for end of the lap spool, lap guiding disks proc vided with hollow sleeves having keyways therein, spool holding spindles slidably mounted in the disk sleeves and spool bushings, a key fitted in each spindle, a spring acting on each spindle thereby normally locking them in engagement with the Spool,

Va doiiing lever actuating each spindle, a

manually operatedlever for exerting pressure at the intersection of said dotlmg levers thereby simultaneously releasing the spindles from the spool, and locking means for the doi'ling levers comprising a spring operated detent located in one lever and acting in conjunction with a hole in the other lever, In testimony whereof, I have signed this specification.-
